Welcome Max. There 3 circuits to a Yamaha G9. #1-the starting circuit, (ie: battery/fuse or fuses/wire harness/key switch/stop micro switch/solenoid and starter-generator. all must work in a series to get the engine to turn over. #2-ignition/spark. #3-charging circuit. If you'd like I'll try to help on the starting circuit first. You must have a volt meter (recommended) or test lite. A service manual would walk you thru "step by step", but some people don't want to spend 85.00 bones. Good luck Dave

Dave will be much more help than me on this but having to stomp on the floor to get it to start sounds like a bad connection at the pedal switch. I would also check the connections at the 10 amp fuse on the driver's side rear fender well. Actually, I would probably start at the pedal switch and work my way to the starter/generator and battery cleaning all connections and making sure I had good contact.

You mention a missing ground cable?
Use one half of a jumper cable and clamp to the motor and the other end to the neg battery post and see what happens just for chits and giggles..

Cool Re: 100$ G9 project plz help

OK so i replaced a 10 amp fuse that was blown thinking that was the problem but no . so i checked the pedal connections and they are clean, also i checked the food pedal switch and that was working. using my test light because brother borrowed the volt meter... i took the light tester and toutched it to the pedal switch wires coming from the resistor and the red wire lights up bright and the orange or brown wire is not as bright just seamed wierd to me (the light tester was on the positive terminal of battery)
thanks for all the info its really helpfull but im thinking i might just start replacing things ie: ignition, resistor, coil, etc. what ya think?


i live near snohomish washington any locals?

I think without proper troubleshooting, you will be throwing good money, and alot of it, at a problem that could be as simple as a bad or missing ground or bad connection!!!

You also might be money ahead to take it to a shop and let them check it/repair it if you gon't want to take the time to check it and before putting on the parts replacer hat. just my .02

Do you have any accessories grounded to the frame on this cart? If so, ground any and all of them directly to the neg. terminal on the battery.
